Flutter 20 issues were found when checking AAR metadata

Hola, si de casualidad te sale este mensaje al querer compilar app android: 

":flutter is currently compiled against android-31."

Lo que debes hacer es borrar cache para que el app apunte a la version correcta de android en caso lo haga y sigue el problemas hay 2 opciones ir a ubicacion del paquete en el cache de la pc y borrarlo o editar el archivo que por error aun apunta al Android 31 y poner la version que ocupas (35 en mi caso)

Si te hes de ayuda comparto mensaje completo:

1.  Dependency 'androidx.fragment:fragment:1.7.1' requires libraries and applications that

           depend on it to compile against version 34 or later of the

           Android APIs.

           :_flutter is currently compiled against android-31.

           Recommended action: Update this project to use a newer compileSdk

           of at least 34, for example 36.

           Note that updating a library or application's compileSdk (which

           allows newer APIs to be used) can be done separately from updating

           targetSdk (which opts the app in to new runtime behavior) and

           minSdk (which determines which devices the app can be installed

           on).
